Abstract
An algorithm is disclosed which effectively removes the knurled annular portion on the bottom of a glass or plastic bottle which is located at an inspection location where diffused light is shown through the bottom of the bottle and is observed by a camera looking down through the bottle opening. The annular area is unwrapped and differenced to eliminate the knurling so that defects can be defined.
